What are the Newton's laws of physics?

* Newton's First Law of Physics.

  An object in motion will remain in motion and an object at rest will remain at rest unless acted upon by an outside force.

* Newton's Second Law of Physics.

 The net force of an object equals it's mass times it's acceleration.

* Newton's Third Law of Physics.

  When one object exerts a force upon a second object, the second object exerts an equal and opposite force upon the first object.
